Taking Polygonatum odoratum (Mill.) Druce as experiment materials，the effects of rooting powder with 0，25，50 and 75 mg/L four different concentrations，on the growth of its overground part and newly grown rhizome were studied.The results showed that the production and the number of the newly grown rhizome of Polygonatum odoratum (Mill.) Druce could be increased significantly by treating the seeds with ABT of the concentration of 25~75 mg/L.Soaking the seeds with ABT of the concentration of 50 mg/L showed the most obvious results.The production was increased by 20.6%~46.6% compared to the control group.The increase in production was mainly achieved by the increase in the number of rhizome.To some extent，ABT could help increase the germination rate.But its effect on plant height and the number of leaves was not obvious.
